This implies, for instance, that 1 kilogram of matter is equivalent to an energy E = (1 kg)×(3×108 m/sec)2 = 9×1016 kg m2/sec2. An energy of 1 kg m2/sec2 is known as 1 joule, for short. The joule is not a unit of energy that is used much in everyday life.

## What is produced when 1 kg of mass is fully converted into energy?

**9×108J**.

## What happens when mass is converted to energy?

**Mass conservation** breaks down when the energy associated with the mass of a particle is converted into other forms of energy, such as kinetic energy, thermal energy, or radiant energy. Similarly, kinetic or radiant energy can be used to create particles that have mass, always conserving the total energy and momentum.

## Which mass is converted into energy?

**The sun** produces its energy by the conversion of mass into energy through the process of nuclear fusion. Mass-energy equivalence is the famous concept in physics represented mathematically by , which states that mass and energy are one and the same.

## How much energy is in a kg?

This implies, for instance, that 1 kilogram of matter is equivalent to an energy E = (1 kg)×(3×108 m/sec)2 = **9×1016 kg m2/sec2**. An energy of 1 kg m2/sec2 is known as 1 joule, for short. The joule is not a unit of energy that is used much in everyday life.

## What is C in E mc2?

An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is **the speed of light squared**, or multiplied by itself.

## Can we convert mass to energy?

First discovered by Einstein more than 100 years ago, it teaches us a number of important things. **We can transform mass into pure energy**, such as through nuclear fission, nuclear fusion, or matter-antimatter annihilation.

## Does all energy have mass?

**Energy does not have a mass**. But mass is a form of energy. Rest mass of a particle is one form of energy. … Relativistic mass of a particle is another form of energy which happens to be the kinetic energy of the particle.

## Why is C Squared?

Now we’re getting to the c² part of the equation, which serves the same purpose as the star-on and star-off machines in “The Sneetches.” The c stands for the speed of light, a universal constant, so the whole equation breaks down to this: **Energy is equal to matter multiplied by the speed of light squared**.
